I hate those cameras more than most people do. That being said, I can’t condone physical violence on the operator.
How do we know that this murder had anything to do with the victim’s role as a contractor for speed cameras? There may well be another motive having nothing to do with his job, such as a feud over money or a woman. We should not assume that he was killed by the stereotypical angry white male who hates government intrusion.
When I hear that the cameras are being taken out, I think what a great thing. But, when someone kills another human being over it, that is just sickening. The victim was on the phone with his wife at the time he was killed, as well.
